Bump for some help plz...

I've been trying to get this overclocker all night now and nothing.
I've updates the bios still no joy!, I can't get 4ghz stable not unless it has 1.35v.
Please help... Might have to go back to my i5 760 at this rate!.

Right once you have done that then you play your favourite game. Or what ever is your most stressful application that you use daily. That is your stability test. Those other applications that people swear by are a total waste of time with SB all they show is that SB can complete ten million hours of what ever stress test it is. And then promptly fails playing WOW on line. Real world for real world stability. I will check back after 8 tonight then.

Later.

Right the first thing you need to do is download the latest version of the EFI Hybrid OS based bios. It works a dream with the Z68X board you have.

Find it HERE


Latest BIOS GA-Z68X-UD3P-B3 bios (F4c): http://91.121.148.119/downloads/BIOS/Z68XUD3P.F4C


  1. Update your BIOS to the latest offical version
  2. Boot into BIOS
  3. Reset to default values
  4. Boot into OS
  5. Install the EFI OS based BIOS
  6. Select Profile 1 for your ram
  7. Change your CPU multiplier to the desired number in your case 40x
  8. Go to the voltage section
  9. LLC 5
  10. VCore 1.4
  11. Vtt auto
  12. PLL 1.76
  13. All the rest on Auto
  14. Now go to advanced CPU functions
  15. Disable turbo
  16. Leave all the rest auto
  17. F10 and enter

I will check back a little later to see how it goes
Now lets start from the beginning if you do not mind.

Hello 1day,

I have done all of the above but set my vcore to 1.35v and up to the multiplier to 46, and set the DRAM volts to 1.5v as when i was checking it it was saying "1.65v".

So at the mo I'm running 4.7ghz @ 1.36 stable so far

if i go any higher with them volts and upping the multiplier my system wont boot at all.

What is Vtt? can i turn that up or should i just leave it at auto what is 1.05v

any more tips?..

Thank you.

Thank you very much 1Day.

Temps will not be a problem as i am running on a custom waterloop.

I bring the vcore down n by a notch now, so far i am at 1.32v, temps with that r idel 25'c and full load 45'c.

I've seen people push the SB chip to 5ghz + on silly amouts of vcore. I've try all the way upto 1.5v and still can't get 5ghz why is that?..

once again thank you for your time and info :).

With SB the limiting factor will be the CPU and not the motherboard as a rule. You might find some slight variations between max with different boards. 10MHz here or there. But statistical that is not significant.

I did read that somewhere else, it's like 90% of it from the cpu and 10% from the mobo.

Thank you 1day for your help yes2day, :).

I'm now stable at 4.7Ghz @ 1.33v with LLC it takes me to 1.36v.

Thank you 1day.
